fish, and it also captures fish. Not only is this animal partially
aquatic, but it can climb well  " they make their homes in. trees,
but carry on their business elsewhere/* The animal can be
readily tamed, bat is a tiresome pet on account of its insatiable
curiosity and its skill in the use of its hands, which enables it
to unlatch doors and generally to pry about everywhere. The
Haccoons are mostly nocturnal creatures.

The genus jBassaricyon, 1 includes two species, both American,
JB. alleni being from Ecuador, and B. gdbbii from Costa Itica.
They have so much the aspect of a Kinkajou that a specimen,
which arrived at the Zoological Gardens, was presented and
entered as one of those animals. Nevertheless there are many
differences between the two genera. The tail of Eassaricyon is

not prehensile, and the animal, as will be seen from Fig. 214,
has a sharper snout ; the brain, is more like that of ^Bassariscus.
The likeness to Oercoleptes can hardly perhaps be regarded as an
example of " mimicry " since the forms are so nearly related, and
the advantage of such an imitation remains to be proved. The
muzzle of "Basscvricyon is grooved ; the ears are fairly large ; the
soles of the feet are naked ; there is but a single pair of teats.
There are two molars and four premolars to each half jaw.
The dorsal vertebrae are thirteen in number ; nine of the
ribs reach the sternum. The slenderness and convexity of the
lower margin of the lower jaw, as well as the feeble angular
process, distinguish this genus from its undoubtedly near ally
Oercoleptes. The dental formula also is different.
JBassariwus has a ringed tail like a Haccoon, and is also
American in range ; it furthermore agrees with the Kaccoon in
